CHARLES T. BRUES 
size, oval; with a long costal vein, four light veins and no mediastinal 
vein although the third vein and humeral cross-vein are well marked at 
this point. Front provided with a small ocellar tubercle and distinct median 
frontal groove. Proboscis enlarged and heavily chitinized. 
In general appearance the type species is similar to Hypocerct or 
Phora, except for the bare legs, proclinate frontal setæ and elongated 
chitinized ovipositor. In my table of genera (Trans. Am. Ent. Soc. XXIX, 
337.) it will run to Syneura Brues from which it is distinct by its long- 
costa, four light wing veins, short front, elongated ovipositor and diffe¬ 
rent habitus. 
I think without doubt that Yerrall’s Phora formicarum (Jour. 
Linn. Soc. XIII, 258 [1877]) belongs in the present genus, although the 
description does not indicate whether the anterior frontal setæ are pro¬ 
clinate. All other characters are so strikingly similar, that I hardly hesi¬ 
tate in placing the two together. 
Plastophora Beirne n. sp. 
Female. Lenght 1*75 mm. Yellow, marked with black as follows: 
frontal tubercle ; namrw apical band on first abdominal segment, and 
wider apical bands on second to fourth segments fading out laterally ; 
lateral angles of third to fifth segments ; ovipositor, except tip, and four 
pairs of lateral spots on venter. Front as wide as high, the anterior pair 
of proclinate setæ weak, the lateral pairs of next row above forming with 
the upper proclinate ones an arcuate row; following row straight; ocellar 
row of six. Post-ocular cilia very delicate above, stronger below; cheeks 
each with a pair of downwardly directed macrochætæ. Antennæ small, 
arista nearly bare. Palpi moderate, bristly at the tips only. Proboscis en¬ 
larged, as long as the head height, hardened and polished. Thoracic dorsum 
rather thickly covered with fine black hairs, bearing three narrow, obso¬ 
lete longitudinal vittæ of gray near the middle ; one pair of dorsocentral 
macrochætæ and two scutellar bristles. Ovipositor about as long as head 
height, slender, gradually tapering toward tip ; black portion truncate, the 
smaller pale tip projecting. Legs stout, the femora moderately thick, 
posterior tibiæ faintly setulose. Wings yellowish hyaline, the costal cell 
reaching to the middle of the wing (its cilia completely rubbed of in the 
type specimen although I suspect they were very short and closely placed) ; 
first vein ending midway between the humeral cross-vein and tip of third ; 
third vein not furcate, distinctly stouter than the costal vein ; fourth vein 
sharply curved at base and straight at apex; seventh vein distinct. 
A single female, Friedrich- Wilhelmshafen, New Guinea (Biró, 1901).
